Description: 本程序是一种先进的充气电缆气压自动监测系统的程序。其特点是可以对电缆线路上各点的气压值进行24小时实时监控。使管理人员可以实时掌握电缆内的气压情况,及时发现漏气隐患,从而保证通信畅通。 系统采用性能价格比较好的AK-3 型压力传感器,直接输出0~5V电压信号。电压信号的转换采用串行接口的12位A/D转换器TLC2543,精度和速度都能很好地满足系统要求。仪器的CPU采用目前低价位但技术十分成熟的AT89C51,仪器的LED数码管显示/驱动芯片采用接口简单但功能强大的HD7279。本系统提供日历时钟电路,在方便用户确定时间的同时,还可以为定时通信提供依据;在发生报警时还能向上位机提供确切的报警时间。同时系统还设计了RS-232总线的通信接口电路,每到整点就要向上位机发送各路气压值,供上位机记录分析。 本系统软件分两大部分,键盘中断和定时中断。工作流程是这样的:每50ms就要进行AD转换,尺度变换,比较是否越位,是否报警等操作,如果有按键动作,执行键盘中断程序。键盘解释在5s之内有效。 如需详细的硬件电路与说明文档,请与作者联系!

Description: 传统的有声无声检测方法只能在相对安静的环境下(<20dB)进行。因此传统方法不能满足噪声环境下的检测要求;另一方面,一直以来,单通道语音增强没有取得突破性进展,一个很重要的原因是没有找到高效的有声无声检测方法。研究了一种有声/无声检测算法是根据信号低频带、高频带短时能量包络的动态变化范围来判别噪声和含噪语音。对每一帧输入信号,通过与预先设定的一系列门限值比较来判断该帧是信号帧还是噪声帧。本设计使用了这种检测方法,选用北京瑞泰创新科技有限公司开发CETECK-VC33-D板,配合自己制作的前端抗混叠滤波放大器和后端的结果演示模块(利用单片机AT89C51制作跑马灯来演示)来实现整个算法。-err
